Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed July 8. 1907. Serial No. 382.794:-

To all whom it may concern:

Be it known that I, ROBERT C. BRYANT, a citizen of the United States,residing at Faroe, in the county of Smith and State of Mississippi, haveinvented certain new and useful Improvements in Brushes, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to improvements in brush heads for scrubbingbrushes, stable brushes and the like.

The object of the invention is to provide a device of this characterwhich is of simple, strong, durable and comparatively inexpensiveconstruction and upon which the scrubbing material may be readilyreplaced when worn.

With the above and other objects in view the invention consists in thenovel construction and the combination of parts hereinafter describedand claimed and illustrated in the accompanying drawings, in whichFigure 1 is a plan view of my improved brush Figs. 2 and 3 are sectionalviews taken on the planes indicated by the lines 2, 2 and 3, 3 in Fig.1, and Fig. 4 is a detailed perspeotive of one of the pivoted bars ofthe brush head.

In the drawings 1 denotes my improved brush head which comprises frontand rear side bars 2, 3 and a pluralityof intermediate bars 4. Thesebars 2, 3, 4 are arranged in spaced parallel relation and between themare a plurality of pivoted bars 5 which are adapted to retain or securethe brush material 6 between the relative stationary bars 2, 3, 4 asmore clearly shown in Fig. 2. The brush head also comprises two endbolts or equivalent clamping devices 7, 8 which serve to unite saidbars. The bolt 7 passes through transverse alined apertures in the bars2, 3,

4, 5 .and also through spacing washers 9 arranged on the opposite sidesof each of the pivoted bars 5. Said bolt 7 not only serves as a clampingdevice for one end of the brush head but also as the pivot for theswinging bars 5 as will be readily seen upon reference to Fig. 1; Thebolt 8 passes through alined transverse apertures in the bars 2, 3, 4and also through spacing washersv or blocks 10 arranged between saidbars and having concave sides so that they are smallest at theircenters. The pivoted or swinging bars 5 are preferably formed by bendingstrips of sheet metal into substantially U form and arranging them sothat their closed portions 11 are uppermost as seen in Fig. 2. Thelongitudinal edges of the depending side portions of the bars 5 areflared outward and are notched or serrated to provide teeth 12 whichbite the brush material 6 and prevent the same from slipping when it isclamped in position. Formed in the upper edge of each of the bars 5adjacent to its free end is a notch or recess 13 which is adapted toreceive the reduced central portion of one of the spacing blocks orspools 10 and which is of such depth that a locking pin 14 may beinserted endwise intosaid bar 5 and above said block or spool as clearlyshown in Fi s. 1 and 3. These locking pins, which may To of any suitableconstruction, will effectively connect the free ends of the bars 5 tothe spacing blocks 10 and at the same time permit of the ready disengaement of said bars so that the brush materia 6 may be removed hen worn.

If desired a handle of any suitable form and construction may beprovided forthe brush head but the handle illustrated comprises a bar 15secured upon a resilient tang -16 formed on one end of an angle plate 17secured upon a centrally disposed transverse bar 18. This bar 18 isarranged in the upper portions of the outermost bars 2, 3 which latterare of greaterwidth at their centers than the intermediate bars 4, andit is passed through an opening'formed in the bar 3 and is retained insuch opening by nails or other fastenings 19. The inner or rear end ofthe bar is formed with an enlargement or head which bears against theouter face of the bar pin and the forward end of said bar 18 is adaptedto slide in a transverse opening or seat formed in the upper edge of thebar 2. It is retained in the latter by a plate 20 secured to the upperedge of said bar 2 as clearly shown in Figs 1 and 8.

The brush material 6 may be corn shucks, fiber, bristles or any othersuitable material which will serve the purpose for which the brush isdesigned and which may be folded over the upper rounded edge 11 of thebars 5 and clamped between the teeth 11 of the latter and the oppositesides of the stationary bars 2, 3, 4, as seen in Fig. 2.

In making up my improved brush the nuts upon the threaded rear end ofthe bolt 7, 8 are preferably loosened, and the pins 14 are removed sothat the pivoted bars may be swung outwardly to receive the brush material 6. When the latter has been arranged .upon the bars 5 they areswung inwardly between the bars 2, 3, 4 so that their notched ends 13engage the spacing blocks or spools 10. The locking pins 14 are theninserted in the ends of the bars 5 and above said blocks 10 as shown inFig. 1, and the nuts of the bolt 7, 8 are then tightened so that thebrush material 6 will be efiiectively clamped in the brush head.

Having thus described my invention what I claim is 1. A brush headcomprising relatively stationary bars arranged in spaced parallelrelation, brush material retaining bars pivoted to swing between saidstationary bars and means for retaining said pivoted bars between saidstationary bars, substantially as described.

2. A brush head comprising relatively stationary bars arranged in spacedparallel rela tion, brush material retaining bars pivoted to swingbetween said stationary bars, said pivoted bars being of substantial Ushape cross sections and having their depending longitudinal edgesflared outwardly and notched to provide teeth, and means for retainingsaid pivoted bars between the stationary ones, substantially asdescribed.

3. A brush head'comprising relatively stationary bars arranged in spacedparallel relation, elements for spacing said bars apart, channeled barspivoted for swinging movement between said stationary bars and adaptedto retain brush material between the latter, said pivoted bars beingnotched to receive said spacing elements, and locking pins inserted inthe ends of said pivoted bars and engaged with said elements,substantially as described.

4. A brush head comprising bars arranged svspoe in spaced parallelrelation, bolts passed through said bars adjacent to their ends, brushmaterial retaining bars pivoted at one end upon one of said bolts andadapted to swing between said spaced bars and means for detachablysecuring the free end of said pivoted bars to the other of said bolts,substantially as described.

5. A brush head comprising bars arranged in spaced parallel relation,bolts passed through said bars adjacent to their ends, means upon saidbolts for spacing saidibars apart, brush material retaining bars pivotedat one end upon one of said bolts and adapted to swing between saidspaced bars, said pivoted bars being notched to receive the spacingmeans upon the other bolt and looking pins inserted in said pivoted barsand engagement with said spacing means, substantially as and for thepurpose set forth,

6. A brush head comprising bars arranged in spaced parallel relation,means arranged at the opposite ends of said bars for uniting and spacingthem apart, pivoted bars arranged to swing between said parallel bars,brush material folded over said pivoted bars and retained between saidparallel bars, a transverse bar secured to one of the outermost parallelbars and slidably engagedwith the other of the outermost parallel barsand a handle carried by said transverse bar, substantially as described.

In testimony whereof I hereunto affiX my signature in the presence oftwo witnesses.
